[5 pоints eаch]: A sаmple оf blоod pressure meаsurements with mmHg are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement.Systolic, x:    118    128    158     96     156    122    116    136     126    120Diastolic, y :    80      76      74      52      90      88      58      64      72      82From the data,∑x=1276    ∑ x2=165936∑y=736      ∑ y2=555681) Find the coefficient of variation (CV) for each of the two samples.    [Round to one decimal place]2) Which data (Systolic, x or Diastolic, y) has larger variation?
